Speed dial, theme background, extension disappeared

Well, I don't know exactly what happened, if an update have been instaled or what, but until yesterday everything was ok.

Today, when I first turn on my laptop and open my Opera, the theme backgroud has changed itself, speed dial folders disappeared (the other sites in speed dial remain there, just the ones inside folders disappeared - I checked that the disappeared ones still appear in my Opera Stash, but in a session called "Others Speed Dial (as i'm using a version in portuguese, im not sure if this is the correct name).

Beside that my extensions also disappeared. I'm not sure if there is any file corrupted causing this, but it seems like if a different user was accessing opera, but I dont know if this is possible.
